Support simple toString on objects generated by Data Modeler

In Drools Guvnor 5.5.0, I was able to print a Object that I got using FactTypes. Now in 6.0.x, we are directly referencing objects generated by the Data Modeler via the generated jar. However, now we can no longer see which objects we are getting without implementing our own external toString(Object obj) method (i.e. generically using reflection or specifically referencing each field in the modeled object).

Please update the data modeler to generate a simple toString() method that will give visibility into the data members of the object.
